If Saturn Valley was a stage, wouldn't there be an infinite amount of Mr. Saturns waddling around your feet?
That's get so much of my yes!
Also my stage speculation:
Big Blue-Ordeal for the fabulous return of a more fabulous looking Big Blue!
I predict a traveling stage in the form of a minecart level considering their importance to the overall series which has railroad track you can fall through and the main platform is a group of 5 minecrafts. This goes through DK Island and the FD form is a platform made of railroad tracks.
I predict Dangerous Dinner as the stage, more specifically the top of the volcano where you fight Landia, and Landia and the Lor Starcutter make appearances battling in the background.
Area 6, very epic area full of Andross's men and Arwings occasionally battle in the background
The Very Loooooooong Cave, it's a stage that scrolls slowly but stops at certain points in the cave to allow for fighting. Obstacles include lava, Shy Guys, Boo Guys, Pyro Guys, and Chomp Rocks.
An actual Ice Climber level looking stage embedded in an ice cave with NO ICE PHYSICS (plz Sakurai stahp) where there are the floating cloud like platforms moving, the breakable blocks on either side of the bottom of the stage, and the permanent blocks being the main platform. Also, the enemies and animals from Ice Climber are hanging out in the background of the stage near an icy lake.
Either the Golden Pyramid from Wario Land 4 or Diamond City, a traveling stage atop Orbulon's Ship, depending on what Sakurai wants to represent.
Saturn Valley, enough said...........BOING! HONK HONK!
